Question

Two Arithamatic sequence with common difference is 5 their. 6th and 9th terms are equal what is difference between first terms

Answer 1

Answer:

The difference between first terms is 15

Step-by-step explanation:

Let x and y be the first terms of the two APs. Their common difference d = 5. Now

6th term of First AP = 9th term of second AP

or x + 5d = y + 8d

or. x - y = 8d-5d = 3d

or. x - y = 3*5

x-y = 15
